Backtesting is the process of testing a forex robot/trading strategy with historical data available in the MetaTrader 4 terminal, to see how it would have performed in the past. Theoretically, if a forex robot (called also expert advisor) worked well in the past, it will continue to do so in the future. Therefore back-tesing is very important and must be done correctly.
Although that WallStreet Forex Robot 2.0 Evolution and the other robots WallStreet ASIA Evo and WallStreet Recovery PRO Evo are already optimized and you don't need to make any optimizations and imrpovements you may want to try some custom settings or to test the robot on unsupported pairs. Therefore you have to know how to backtest the robot correctly. Otherwise you may get unexpected results.
Please, do not forget to activate your demo, or real account, even if you only wish to backtest WallStreet 2.0 Evolution!
If you wish to backtest WallStreet 2.0 Evolution, first you should download history from the MetaTrader history center: click Tools -> History Center, or press the "F2" key of the keyboard. In the list, find the currency pair that you wish to backtest and double click to expand it. Click "1 Minute (M1)" and then click "Download". When the download process is finished, double click on "5 Minutes (M5)” and "15 Minutes (M15)" to convert the M1 data. Close the "History Center" window. Please check the below image:
To open the "Strategy Tester" window click the "Strategy Tester" button of the MetaTrader menu, or press "Ctrl+R" on the keyboard. In the "Strategy Tester" window chose "WallStreet 2.0 Evolution ", chose one of the supported currency pairs (GBPUSD, EURUSD, USDJPY, USDCAD, USDCHF, AUDUSD, NZDUSD and EURJPY), chose M15 timeframe, chose the method "Every tick ...", as shown below. Enter 20 for Spread. Click "Start" to start the backtest. Please check the below image:
The backtest by "Every tick" is the most precise, but it is very slow. If you wish to save time you can run the backtest on M1 timeframe by "Open price only ..." method and this will be correct too.
